CustomizableMultiselectField class
A FormField that contains a CustomizableMultiselectWidget.
This is a widget that wraps a CustomizableMultiselectWidget widget in a FormField.
A Form ancestor is not required. The Form simply makes it easier to save, reset, or validate multiple fields at once. To use without a Form, pass a GlobalKey to the constructor and use GlobalKey.currentState to save or reset the form field.
